hello people! basically, I'd like to know the differences between the macbook pro 13'' 2.6 GHz i5 and it's cpu upgrade the i7, and if they would fit my needs. what I intend to do with this computer is photo and video editing (I travel a lot and I cannot have a larger screen or desk computer). but in the other hand I'd like to do some gaming and I'm worried that since the macbook is using the intel iris technology, it wouldn't work properly for the photo/video editing and/or the gaming thing. any advice is welcome ! thanks in advance.
